Question

Probability is:
a. The measure of how likely an event is to occur.
b. The ratio of total possible outcomes to desired outcomes.
c. Not conveyed as a decimal or a percent.
d. None of the above.

Answer 1

Answer:

Option a) The measure of how likely an event is to occur.      

Step-by-step explanation:

We define probability of an event as:

• It tells us how likely the event is to occur.

• Mathematically, it is defined as

$\text{Probability} = \displaystyle\frac{\text{Number of favourable outcomes}}{\text{Total number of outcomes}}$

• It ranges from 0 to 1.
• An event with probability with 0 probability is impossible event and an event with probability 1 is sure event.
• Probability of an event can never be negative.
• It can be conveyed in decimals and percentages.
• It tells us how often a event will happen.
• Thus, the correct interpretation for probability is :

Option a) The measure of how likely an event is to occur.
